CHARCOAL-BURNING APPARATUS. Y

Be it known that 1 WiLLmM H. MCGEE, a citizen of the United States of America, and resident of Austin, in theV county of Hayes and States of Texas, have inventedl certain new and useful mprovements in Charcoal-Burning Apparatus, of which the following is a specification. f

This invention relates to charcoal burning and particularly'to burning devices known as charcoal pits, the said invention having for its object the provision of novel means whereby a superior product results `while at the saine time, the quantity produced from a given amount of raw material is greatly.

increased as compared with the products resulting from known methods and apparatus.

rlhe invention has for its object the provision of a pit or furnace having refractory walls of strong and durable structure which will withstand the impact of the raw material when it is delivered to the pit withoutV ln describing .the invention in detail, ref- .erence will be had to .the accompanying drawings'forming part of this specification lwherein like characters denote corresponding parts in the several views, Y and in which- Figure 1 illustrates a plan view of a charj v coveredwith earth, straw or bark to, prevent j vfree burning as is now commonly done, so

that much labor and material is-saved, while f coalpit and a roadway leading thereto; l, Fig. 2 illustrates a view in elevation of the pit and the parts associated with it and the roadbed in section;

Fig. 3 illustrates a sectional view on the line 3.-3 of. Fig. 1, and

Fig. 4e illustrates a sectional view on the line de@ of Fig. 1.

l/Vhile proportions do not enter into the l limitations with respect to the construction of the invention, it has been found in practice thatv the best results are attained by having a pit which is not more than eight feet in depth and ten feet square with the upper surface of thewall about 2J; feet above the specification f Letters raient.

ground. Preferably `thewalls of the pit are formed of concrete, rock, or brick. ,v Y

ln these ,drawings 5 denotes'the pit,f6 the walls of the furnace or containerwhich preferably are in spaced relationto thewalls of the pit to permit the escape of the products of combustion emanated from the smoldering material within the furnace, and

the rear and side walls of the said pit are Y provided with vents or openings 7 each of which is controlled by a damper 8 slidable in4 vertically disposed ways 9'formed in the walls of the furnace, the said dampers being operated by the damper rods 10 projecting at the top of the furnace so that they may be manipulated by kan operator and adjusted to increase or diminish the venting areaof the openings. The top orvupper edges of the walls are recessed to form shoulders 11 constituting seats onwhich the doors 12 may rest, when in their lowermost positions.. One

of the doors 12 mayalso have an aperture la controlledby a'small door 15 which is v hinged as shown in'Fig. 1 so that there may be an opening formed in the roof of thepit throughwhich the contents ofthe pit may door 16 hinged inthe frame 17, and the said be fired. The front of the pit has a large Y large door has a slotor opening 18 controlled l of observation or for creating a draft.

The roof doorsare preferably inftwo sections which overlap tov produce a relatively tight joint and by their use, a dra'ftis so controlled as to sufficiently smother the vfire and cause the burning materia-l to char inf.

stead of toburn freely.y f

By the use of a pit of the character indii y cated, the materialbeing-treated need not be the product is entirely freey of foreign substance and is ofa superior quality compared with that made in the ordinary way. The earth in front of the pit is excavated to a depth equal to the height of the pit so as 'Y to form a roadway or stand for a-vehicle delivering the wood to the'pit as ,shown at 20 and the said roadway is inclined as at 21 and 22 Vin opposite .directions f so .that'a thepit `is such thatk the vehicle or the body thereof will be approximately at the top of the pit for convenient charging of the pit directly from the vehicle.
